  According to the present invention, there is an effect that it is possible to automatically select and record a program that is expected to be of interest to the world among programs broadcast in the same time period.

  A digital broadcast receiving and recording apparatus according to an embodiment of the present invention will be described below with reference to FIGS.

  FIG. 1 shows an HDD recorder 30 with a terrestrial digital tuner (further, a DVD player 22 is added) 30. The antenna 1 receives a terrestrial digital broadcast signal sent from a terrestrial broadcast station.

  The terrestrial digital tuner 2 takes out a signal of a specific frequency from the high frequency digital modulation signal including the video / audio data. Further, the tuner 2 includes a demodulation circuit, a deinterleave circuit, an error correction circuit, and the like, thereby demodulating the selected digital modulation signal and outputting a transport stream.

  An MPEG-TS decoder separation circuit (hereinafter simply referred to as a decoder) 3 converts the transport stream into an MPEG2 (Moving Picture Experts Group 2) video stream, an audio stream, and PSI / SI (Program Specific Information / Service Information). To separate. The AV decoder unit includes a video decoder that decodes a video stream and an audio decoder that decodes an audio stream. Video data output from the video decoder is output to the video processing unit 4, and audio data output from the audio decoder is output to the audio processing unit 5. The PSI / SI includes program information (title, start time, duration, genre information, program content details, etc.) indicating what kind of program each program is. The CPU 13 displays an electronic program guide (EPG) freely designed on each receiving device side on the screen by using an OSD (on-screen display) function and the program information.

  The video processing unit 4 receives the video data of the received video, performs D / A conversion and down-decoding processing, and outputs, for example, a composite video signal. The video processing unit 4 has the OSD function, and synthesizes video based on character information and color information instructed to be output from the CPU 13 with the video data. The audio processing unit 5 receives the audio data output from the decoder 3 and generates right (R) sound data and left (L) sound data.

  The video signal is supplied to the video output unit 11 through the amplifier 7. The audio data is converted into an analog signal through the D / A conversion amplifier 8 and input to the audio output unit 12. A display and a speaker (not shown) are connected to the video output unit 11 and the audio output unit 12 via an AV output terminal (not shown).

  The memory (RAM, EEPROM, flash memory, ROM, etc.) 14 stores various programs and data. For example, application programs and various data are stored in the ROM. When the power of the recorder 30 is turned on, the CPU 13 expands the program and data stored in the ROM to the RAM and executes the program on the RAM. This program includes a driver and a protocol stack for controlling the HDD 17, USB interface 20, and LAN interface 18.

  The remote control transmitter 15 is a transmitter for sending commands to the recorder 30. When a key provided on the remote control transmitter 15 is operated, signal light (remote control signal) indicating a command corresponding to the key is transmitted from a light emitting unit (not shown). The light receiving unit 16 receives signal light output when a key of the remote control transmitter 15 is operated, converts this into an electric signal, performs code analysis, and channel number information specified by the user for channel selection, etc. Is given to the CPU 13.

  A LAN card 19 can be attached to the LAN interface 18. By installing the LAN card 19, an Internet connection environment can be created. The memory 14 or the LAN card 19 includes a server 50 (the server 50 is a search site (search engine providing resource), a ranking site (ranking information providing resource), a site that provides public interest level information of each broadcast program, etc.) A certain installation address (URL) is stored. The CPU 13 activates the LAN interface 18 and accesses the server 50 using the URL when, for example, receiving an instruction from the user or when a predetermined daily date and time is reached. For data communication, for example, based on TCP / IP, FTP (File Transfer Protocol) or HTTP (Hyper Text Transfer Protocol) can be used.

  In addition to performing overall control of the recorder 30, the CPU 13 executes the following processing as processing according to the present invention.

(1) Generation of Public Interest Level of Broadcast Program Using Search Site Using the LAN interface 18 and the LAN card 19, the CPU 13 accesses the search site using the URL and sends a search word. An example of processing contents is shown in the flowchart of FIG. CPU13 extracts the program title used as the said search word from the program information of each broadcast program (step S1). Next, the CPU 13 selects a search site (search engine) (step S2). Search sites (search engines) include, for example, Google, Yahoo, Google, Infoseek, excite, etc. (all are trademarks). The user may select a search site in advance.

  Next, the CPU 13 performs URL encoding processing (step S3). Note that the character code differs depending on the type of search engine (Yahoo, Goo, Infoseek is EUC-JP, and Google, excite is UTF-8 (8-bit UCS Transformation format)). Next, the CPU 13 issues an HTTP Get request packet (step S4). For example, when the search engine is Google and the search word is “project Y”, a request “GET http://www.google.co.jp/search?hl=ja&q=project Y” is issued. Then, the CPU 13 acquires an HTTP Get response packet (step S5). And from this response, CPU13 acquires the number of hits (step S6). For example, if the search engine is Google, “**” in “Swrnum = **” is acquired.

  For example, the CPU 13 performs the hit count acquisition process described above for each program title in the currently held program information. As a result, a numerical value indicating the number of hits for the title of each program can be acquired.

  Based on the above numerical value (number of hits), the CPU 13 considers the broadcast program to have a higher public interest level as the numerical value increases, and generates public interest level information of each broadcast program consisting of numerical values. Here, for example, the value of the hit count itself can be used as the public interest level information of each broadcast program. Of course, the interest level (numerical value) may be generated by other methods. For example, the largest number of hits may be 100, the lowest number of hits may be 0, and the number of other hits may be quantified.

  In the above example, the program title is a search word, but the present invention is not limited to this. For example, the name of the performer in the program may be used as a search word, and the degree of public interest in the program may be generated based on the search result. Moreover, it is good also as acquiring the search result by AND and OR of several words, such as a title name, a broadcast station name, and a program genre. Further, it is not limited to the HTTP protocol Get request, and is not limited to a general-purpose search engine. A protocol other than the HTTP protocol may be used in accordance with the protocol supported by the HTTP server.

(2) Generation of public interest level of broadcast program using ranking site The CPU 13 uses the LAN interface 18 and the LAN card 19 to access the ranking site at a URL stored in advance and search for a ranked word. To do. The ranking may be a ranking without any restriction, or may be a specific ranking such as an actress ranking or a preference ranking. An example of processing contents will be described below. CPU13 selects a ranking site (step S11). Examples of ranking sites include Google and Google. The user may select a ranking site in advance.

  Next, the CPU 13 issues an HTTP Get request packet (step S12). Then, the CPU 13 acquires an HTTP Get response packet (step S13). And from this response, CPU13 acquires the word quoted by ranking (step S14). For example, assume that the response is as follows.

<TD class = rankreala = "90%">
<DIV class = realminirankon5>
<SPAN class = "realkey1>
<DIV>
<A
href = "http://search.goo.ne.jp/web.jsp?MT=%BC%E1%CD%B3%C8%FE%BB%D2&amp;from=recentkw&amp;PT=recentkw"> ○ Taro Yamato </A>
</ DIV>
<SPAN>
</ DIV>
</ TD>
</ TR>
.....

  In such a format, search for “PT = recentkw”, and then list the first character string between “>” and “<” (in the above example, ○ Yamataro) in the ranking. As words (hereinafter, abbreviated as RW). The above character strings are also present in other rankings. By repeating the extraction of the character string, all the character strings (words) ranked can be extracted.

  Further, the CPU 13 extracts a program keyword from the program information (step S15). For example, it is assumed that the contents of the program details are “Hideyoshi (Yamataro) and child (松田 花子), Tsurumatsu suddenly, and Nene by Nene ...”. In this case, since one word (RW) listed in the ranking exists in the program details, it is assumed that 1 point is obtained (step S16). Note that a program keyword that can be acquired from program information, such as the word, title, name of the lead actor, and broadcast station name in the program details, may be abbreviated as BW.

  If the total number of words (RW) listed in the ranking is N (RW = N) and the total number of program keywords (BW) that can be acquired from the program information is M (BW = M), the total of RW and BW In a win (N × M times), the number of matches is detected (step S17, step S18). The total number of coincidence is the number of points (step S19).

  In order to extract words that are nouns from the details of the program details, a technique called morphological analysis may be used. Further, the broadcast station side may add the program keyword in advance in the program information in order to facilitate the matching process determination on the receiving device side.

  The CPU 13 performs processing for regarding the total number of points obtained for each broadcast program as the degree of public interest of each broadcast program. That is, a broadcast program having more words in the program information that are ranked in the ranking information obtained from the ranking information providing resource as the information providing resource is regarded as a broadcast program with a higher public interest, and from a numerical value. The public interest level information of each broadcast program is generated. Here, for example, the value of the hit count itself can be used as the public interest level information of each broadcast program. Of course, the interest level (numerical value) may be generated by other methods. For example, the largest number of hits may be 100, the lowest number of hits may be 0, and the number of other hits may be quantified.

  In the above processing example, the ranking is not considered, but the number of points may be calculated in consideration of the ranking. For example, the word ranked first is 100 points, the word ranked second is 99 points, the word ranked 99th is 2 points, ranked below 100th There is one point in the word that is being used. In this case, the score of the word given the highest score may be regarded as the public interest level instead of the score obtained by RW and BW round robin. Moreover, you may produce | generate a public interest degree only by a ranking order.

(3) Provision of public interest level of broadcast program by ranking site itself The ranking site itself may provide the public interest level (broadcast program ranking) of the broadcast program. For example, a questionnaire asking which ranking site wants to watch most among programs scheduled to be broadcast may be constantly performed on the net, and the public interest level of the broadcast program may be generated from the answer. Here, for example, the value of the number of responses itself can be used as the public interest level information of each broadcast program. Of course, the interest level (numerical value) may be generated by other methods. For example, 100 may be the one with the largest number of first responses, 0 may be the lowest, and the other first responses may be digitized. Note that the ranking site can also generate public interest level information of each broadcast program by the methods (1) and (2) described above.

  The CPU 13 uses the LAN interface 18 and the LAN card 19 to access a ranking site that provides the public interest level of the broadcast program at a URL stored in advance, and acquires public interest level information (numerical value) of each broadcast program. The information is stored in, for example, the memory 14 (nonvolatile memory or the like).

(4) Adjustment of program interest level and public interest level according to user's preference Just because the public interest level of a certain program is high, the user's interest level for the program is not necessarily high. On the other hand, the user may want to watch a program with a high level of public interest as much as possible. Therefore, the higher the public interest level of the program and the higher the interest level of the user, the more the program should be recommended to the user. In other words, even if the degree of public interest of a program is high, if the degree of interest of the user is low, processing for lowering the order of the program to be recommended to the user is performed.

  In order to measure the user's interest level for a certain program, a so-called user preference determination method is used. For this method itself, a conventional method may be used. For example, as a simple method, the genre of the program is listed (displayed) on the user setting screen of the receiving apparatus, and one or a plurality of genres that the user likes are selected. The CPU 13 gives “0” to the program of the selected genre, and gives “−20” to the program of the genre not selected. That is, “0” and “−20” are user interest level information of each broadcast program including numerical values. Then, the CPU 13 performs a process of subtracting the user interest level information (numerical value) of each broadcast program from the public interest level information (numerical value) of each broadcast program, so that each broadcast program consisting of the user's numerical value is obtained. Generate recommendation level information. That is, if it is a program of the genre selected by the user, the public interest level information (numerical value) becomes the recommendation level information for the broadcast program of the user as it is, and if it is a program of the genre not selected by the user, A numerical value obtained by subtracting “20” from public interest level information (numerical value) is the recommendation level information of the user regarding the broadcast program. This process corresponds to correcting (weighting) the public interest level information of each broadcast program with the user interest level information of each broadcast program. If the process corresponds to such correction (weighting), the process is not limited to the above-described subtraction process, and a process using multiplication or division may be performed.

  The method for determining the user's preference is not limited to the above genre selection, and the user's favorite broadcast station can be input by the user. In this case, for example, “0” is given to the program of the selected favorite broadcast station, and “−10” is given to the program of the broadcast station that was not selected. Processing may be performed by combining such a favorite broadcasting station and the genre.

  In addition, user preference is automatically determined based on digital broadcast viewing history and digital broadcast recording history (total viewing / recording time within a predetermined period, number of channel selections, etc. for each program) instead of user input. You can also. Specifically, it can be considered that the longer the total viewing / recording time within a predetermined period and the greater the number of channel selections, the higher the user's preference for a program or broadcast station. Also in this case, the user's preference can be set as user interest level information of each broadcast program. Further, it is possible to estimate a genre, a broadcasting station, a time zone, etc. that the user likes from the viewing history of digital broadcasting and the recording history of digital broadcasting. For example, each genre of each recorded program is stored, and the total recording time or the total number of recordings can be set as the user's genre preference within a predetermined period or from the beginning. For example, “+20” is given to the top three genres, and “+10” is given to the next three genres. For a genre that has never been viewed, for example, “−20” is given.

  In addition, when there are a plurality of users for one receiving device, a user input method on the above-described user setting screen or the like is used to obtain a preference level (user interest level information of each broadcast program) for each user. It is easy to input a user name (including a nickname) prior to this input. If the degree of preference for each user can be obtained, the degree of recommendation for each program can be generated for each user. In an automatic recording process to be described later, an automatic recording according to the degree of preference for each user can be performed by obtaining input of user specifying information prior to the execution of the recording.

(Random recording)
The CPU 13 selects a broadcast program having the highest degree of public interest in the broadcast program (which may be based on the user's recommendation level information about the broadcast program; the same applies hereinafter) among the currently broadcasted broadcast programs. To record. For example, a button such as “automatic recording” is provided on the remote control transmitter 15. When the CPU 13 detects that the user has pressed the button, the CPU 13 may perform recording by performing the above-described channel selection process.

  Furthermore, the CPU 13 starts the timer at the same time as performing the above-described channel selection process, and when the set time elapses, the broadcast program having the highest degree of public interest in the broadcast program is broadcast among the broadcast programs being broadcast at that time. Select and record.

  FIG. 4 is a flowchart showing the above processing contents. For obtaining the automatic recording setting conditions performed in step S21, the CPU 13 selects, for example, the channel update interval (previously set time) and the target network from the contents (stored in the memory 14) set in advance on the user setting screen. It is processing. The selection of the target network is any one of terrestrial digital broadcasting, BS digital broadcasting, and CS digital broadcasting.

  In steps S22 to 25, a process of extracting a broadcast program having the highest public interest level of the broadcast program among the broadcast programs being broadcast at that time is performed. In step S26, the public interest level of the broadcast program is the highest. A process of selecting and recording a high broadcast program is performed. Then, it is determined whether or not the timer output t has exceeded the channel update interval T (step S28). If it has not exceeded and an end event has not been received (NO in step S29), standby and timer update are performed (step S30), and the process returns to step S28. On the other hand, when it exceeds, it returns to step S22. Note that the end event is received when a command to cancel the automatic recording is given by the remote control transmitter 15 (for example, pressing the “automatic recording” button again), and at this time, the automatic recording mode is ended. To do.

  Note that the present invention is not limited to the program switching process based on the timer. The switching from the currently recorded program to the next program to be received and recorded may be performed after the end time of the currently recorded received program or before the currently recorded received program ends. It may be when the program with a higher public interest level or a higher recommendation level for the user than the program starts.

(Reproduction of programs recorded by automatic recording)
(1) The CPU 13 may automatically reproduce only a recorded program in which the public interest level information or the recommendation level information for the user is a predetermined value or more. Here, it is assumed that the public interest level information and the like are set in a range of 0 to 100 as described above. In a program recording performed in a certain time zone, the highest public interest level information or the like may be less than 50 points (reference score) like 45 points. For example, when the highest public interest level information or the like is below 50 points, a setting may be made to skip playback. The reference score may be set in advance on the user setting screen by the user.

  The CPU 13 may present a recorded program in which the public interest level information or the recommendation level information for the user is a predetermined value or more (0 or more, 10 or more, 20 or more, etc.) and reproduce the program designated by the user. Good. For example, the CPU 13 that has received an instruction to reproduce a program recorded by automatic recording presents, for example, a list of recording contents for 6 hours prior to the reproduction, and public interest level information and check boxes for each recorded program. Is also displayed. For example, the user designates a program by operating the up / down broadcast key (puts the cursor on it), plays it by operating the enter key or the like (puts a check mark in the check box), or skips (remarks in the check box). It is determined with reference to the public interest level information or the like. The CPU 13 determines reproduction (or skip) according to the mark of the check box.

(2) The CPU 13 may re-acquire the public interest level information or the recommendation level information for the user even after executing the recording. For example, the CPU 13 holds a numerical value from the past to the present (reproduction time) of the public interest level regarding the broadcast program recorded automatically. And based on the change of the re-acquired public interest level information or recommendation level information for the user and the public interest level information or recommendation level information for the user at the time of recording of the recorded program, it becomes a reproduction target. A first classified program in which a change in the public interest level information of the program or a recommendation level information for the user is within a certain range, a second classified program in which the change is downward, and a third classified program in which the change is upward Of which is determined. Then, the CPU 13 asks the user which classification program is to be reproduced (or all is reproduced) prior to reproduction, or the classification designated by the user based on the contents preset in the menu screen. The program is played back as a playback target. Thereby, it is possible to respond to a user's request to view not only all the recorded contents but also, for example, a program whose public interest level is increasing. It should be noted that the reserved recording program may be recorded regardless of the public interest level even if a program with an interest level higher than the public interest level of the program exists in another channel.

  In the above embodiment, an embodiment as a hard disk recorder has been described. However, the present invention is not limited to this, and if a small and large-capacity memory is provided, a portable type or a stationary type broadcast receiving device, a mobile phone, a digital broadcast receiving function It can also be configured as an attached car navigation system, personal computer, or the like.
